I would not house males and females together. The males are real aggresive as they mature, and can really stress or cause damage to females. Some people are lucky housing females together but no matter what there is always going to be a dominate dragon in every group. Like I said it's luck, and all depends on the dragons themselves. Some dragons will no matter what you put in the tank will not get along with others. For keeping a group of three you would need a real large enclosure. If you want to house females together your better off getting a cage built rather then buying a glass aquarium it would be a lot cheaper. I do house 2 females in a custom melemine enclosure that is 4x2x2 with areas were they can avoid each other if they wanted. I'm lucky that I have two that get along. My other females are more aggressive and can't be housed with other dragons. So go into it prepared to house any dragons separetly. For single dragons I keep mine in a 3x2x2 custom cage. I always keep males alone except for breeding time.
